DOUBLING AND TWISTING MACHINE Filed March 16, 1931 Patented. Nov. 8, k1932 UNITED STATES PATENT OFFICE FREDERICK KLEIN, OF'COLLEGE POINT, NEW YORK, ASSIGNOR TO SIPP-EASTWOOD COR- i PORATION, OF PATERSONNEW'JERSEY, A CORPORATION-OF NEW JERSEY' x DOUBLING AND TWISTNG MACHINE Application filed March 16, 1931.` Serial No, 523,027.

This invention relates to machines whereby certain twisting and doubling operationsare performed on yarn or thread, and especially to machines ofthe type in which the a. yarn spools or other cores form with a race member for rotating them ontheir own axes an epieyclic train. My invention has for its general object to provide a unit for a machine of this class whereby at the will of the operator the yarns may be individually twisted and thendoubled and the doubled product twisted, or the yarn simply doubled and the doubled product twisted, thus lowering the cost of equipment and reducing floor space, consumption of powery and supervision; wherein the centrifugal forces generated shall be employed to insure a substantially positive drive of each rotary yarn-core-including element; and whereby, Without undue wear and tear or strain of the parts, high speed shall be possible, with consequent increase in production over that obtained from machines at present in common use for performing the operations stated.

Fig. 6 is a left side fragmentary elevation of said bolster and bracket, illustrating cou pling means therefor; and

Fig. 7 is a view, partly in front elevation and partly in section, of-theupper part 0f the unit.

On the rail 1 is secured by a nut 2 a tubular post 3 affording a bearing for the depending stud l of a bracket 5 which may shift-toward A and 'from the driving belt 6 of the machine and is normally 'urged toward the same by a spring 7 coiled about the post and engaged therewith at one end and with the bracket at the other.

Said bracket receives in a hole thereof the lower end of the bolsterv 8for the sun-spindle 9, the bolster having a collar 8a resting on the bracket and held thereagainst by a spring 10 interposed betweenthe bracket and a nut 10a screwed on said end of the bolster. The bolster is secured against rotation in the bracket by a coupling member which may be a plate 11 apertured to receive the said lower end ofthe bolster ('beingclamped between the bracket and spring 10)v and having at one end an upturned flange 11a bearing against the under side of the bracket and formed with an extension or coupling tongue 11b engaged in notches 12 in the bracket and bolster-collar 8a and having at the other end an upturned lug lleengaged in a notch 4a of the` bracket sothat said memberv is itself held from turning. Clamped `between the latter end of said member and the bracket is one of the bent-off ends of a retaining member 13 whose other end is adapted to overhangY a flange k17a on the hub ofk a carrier (to be described) to keep the latter from f rising, though repressible from said flangey in order to permit the carrier to be removed fronithe bolster.

Said carrier comprises, with the sun-spindle, a body member itselfcomprising a sheavelike shell 14 having upper and lower interior disks orwalls 15 and ljoining it to its huby 17, which is pinned on the spindle, said hub having the 4mentioned flange 17a; the shell and its walls are `here shown pinned together, whereas the hub and said wallsare integral, but these are of course immaterial details. The shell 14 is normally held by the spring 7 bearing, sheave-faishion, against the belt, whereby the carrier is rotated. The walls 15 and 16 respectively have radial slots 15a4 and holes 16a vertically alined with each other further, at the inner end of the slots are.

seated in recesses 15b springs 18 whose function will appear. The carrier also comprises bolsters lfor the planet-spindles, each formed 21. In the upper end of the sleeve is held in any way, as by being forced into the sleeve, another outer ball-bearing race 22. The bolster (specifically, its plug has a reduced and underneath-flat seat 20a and a stem 23 depending through hole 16a and on which is a dished spring-washer 24- held against wall 16 by a nut 25 screwed on the stem. The bolster, with its seat resting on wall 16, tends o to stand vertically, though it is mounted for tilt-ing under the influence of centrifugal force in a radial direction (guided by slot 15a) when the carrier is rotated.

In each such bolster, to wit, in the bearings 21-22, is journaled a planet spindle 26 which has secured on its lower end, by a nut 27, an inner ball-bearing rac-e 21a and jammed thereon the inner ball-bearing race 22a, the

-..races 21a and 22a being arranged as complements of the races 21-22, 28 being the balls between the races. Between the two sets of races may be packing 29 for lubricant. Each spindle has a driving whirl 3() flanged at its v.lower end and arranged above the shell 17 and on its upper end it may have affixed thereto, as by being screwed thereon, the supply spool 3l. I term each spindle and core a yarn-core element.

For guiding the yarn there is a guide or 30 spider 32 having yarn guide holes 33 in its several arms. It is formed with a central hub 34- which is bored to receive the reduced upper end of the sun-spindle and counter .bored at 34a to receive a spiral spring 35 35 interposed between the lower end of the counter-bore and a nut 36 screwed on said spindle, wherebyV the spider is normally depressed against .a collar 3'? on said spindle. The hub N:34 has a depending lug 38 which is received 4:0 in aI notch 39 in the collar of such width as to limit rotation .of thespider to degrees, or from the position where its holes 33 vertically register with the planet-spindles to a ...position where they so register with the 45 vspaces between them (there being in the present case four equally spaced planet-spindles and four arms to the spider) and permit doihng of the spools from the planet-spindles.

- y.'Ihe spider may be retained in the first posil tion by a counter-notch 39a into which, under pressure of spring 35', the lug 38 may enter.

The plniiet-spindlen whirls are all equally spaced from the axis of the sun-spindle and of equal diameters, and they are surrounded by an annular race or rino' 40 resting on their lar all the whirls contact therewith.

flanges and having an exterior peripheral groove which is traversed by a pin 4:1; the inner diameter of the ring or race is prefrably such that with their axes perpendicu- A detent in the forni of a linlr l2 attached to an upstanding post i3 on the rail 1 and having a hoolr to engage pin 4:1 is employed to hold i the ring from rotation when the unit is opern gm spinning, doubling and twisting;

when this detent is unhooled from the pin the ring is free torotate around the sunspindle, as when doubling and twisting. The construction is such that the link not only affords a pivotal connection between the race and post when they are Coupled thereby but the link and post have some elasticity, where by the race yields to the vibrations of the unit both diametrically and rotatively of the carrier.

df. is a guide through which the spun or individually twisted, doubled and twisted, or merely d oubled and. twisted, yarn passes up to some receiving spool or the like.

Operation-Uien the carrier is being driven by the belt 6 the pressure of the springs 18 plus centrifugal force acting on what I term the yarn supplies comprising the mentioned yarn-core elements and their bolsters tends to tilt said supplies outwardly in the body of the carrier, holding the spindles whirls against the annular race 40, whereby the planet spindles will be rotated reversely to the carrier if the race 40 is held from rota tion by the detent 42; or, if the race is released by disconnecting the detent therefrom.l since the race is now-free to rotate around the axis of the carrier, the planet spindles will stand non-rotating- In the one case the yarns will be first each individually twisted and then doubled and twisted together, and in the other simply doubled and twisted. The springs 18 are Vpresent mainly to insure driving contact of the whirls with the race when spinning, doubling and twisting at a speed too low to insure such contact being effective as the result merely of centrifugal force; they are usually not indispensable. lVhen doti/ing, the attendant lifts the yarn guide or spider and turns it 15 degrees, thus bringing its arms out of registry with the spools and affording them the necessary clearance for their removal and replacing with iilled spools.

Certain important novel features of my invention will be clear upon comparison of my mechanism with those of the Saracco Patents Nos. 1,096,059 and 1,131,981 in the latter of which is an epicyclic train whose yarn spools or cores are shiftable to different angular relations to the main axis of the train but are suspended for this purpose, and in the former of which they are each tiltable on a support from wnich they upstand but on a hinge. Thus: The race or driver of the epicyclic train is actually carried by the aforesaid suph plies, specilically, in the example, by their yarn-core elements; when the unit is operating for individual twisting, doubling and compound twisting such driver is consequent ly free to shift in any direction relatively to the axis and as an incident of the lateral vibrations of the unit due to its described connections faQ-113 with the supporting structure 1. Said driver is disconnectively connected with its anchorage as 43) so as either to be held from or permitted to rotate with said elements around the main axis of the unit. The parts 23-16a form a longitudinal telescopic connection opposing sliding movement of the bolster in a plane coincident with the axis ofy the carrier but permitting rocking movement thereof in said plane .and also universally so that good driving contact between the yarncore element and race or driver 40 will result. Each tiltable member is supported by an underneath support (Wall 16) so as to stand when the'unit is vat rest ina state of stable equilibrium, because a vertical y.line passing through the center' of gravity (here in the axis of the spindle) passes through the base of its seat 20a. The carrier body, by comprising a cylindrical shell and two disks (15 and 16) traversing its bore and the upper l one of which guides the aforesaid tiltable members radially and the lower one of which forms a telescopic joint with each such member.l is well adapted to withstand the forces,

mainly centrifugal, active thereon. e Given a carrier having bolsters for said elements, such carrier has means, afforded by its shell,

' tohouse the bolsters and consequently th lubricant contained therein.y y

In certain aspects of my invention it is only material,'as betweenfthe driver 10 and the carrier andin order that the yarn-core ele? ments be rotated in the carrier, that one of them rotates with reference to the other.
